We’ve all experienced the “ick” factor — that queasy feeling that a company has just a bit too much information about you. Sure, you love that Apple‘s Genius has figured out what music you like, and recommends artists you may not yet have discovered. Yes, you like the book recommendations that pop up on Amazon.com, and tolerate eBay’s constant suggestions based on your past purchases (who can’t use another baseball jersey?) Maybe it was a tad creepy that Netflix Inc. recommended a slew of criminal procedurals shortly after you watched a two-day marathon of Law & Order Criminal Intent episodes while recovering from a flu bug. (See “Why Netflix Thinks I’m Gay,” bit.ly/LTN1210b, and In re: Netflix Privacy Litigation www.videoprivacyclass.com.)

It was definitely over the top that you found your picture in a Facebook advertisement for that product that you had “liked” (bit.ly/LTN1210e).
